摘要： [Object]
To effectively improve torque of a motor, the maximum rotation rate in driving with no load, and output at a high rotation rate, while suppressing torque ripple, noise, or vibration of the motor.
[Solution]
A brushless motor 301 has an armature iron core 310 wound with armature windings including plural winding sets 311 and 312 each of which includes multi-phase windings. Voltage application means 302 applies voltages to the plural winding sets. Control means 303 calculates a voltage command for the plural winding sets, and controls the voltage application means based on the voltage command. The control means 303 controls the voltage application means 302 so that induced voltages generated in the plural winding sets by rotation of the brushless motor have a trapezoidal waveform and a phase difference between the voltages for the plural winding sets becomes a value that reduces torque ripple caused by the induced voltages.-
